the whole number 113.101.375 only has one possible option letter which is A and that is a twin port 1600 head, according to my list. So though I can't explain why yours are marked 11 and 22 I think it's 99% certain they are twin port 1600 heads.
Yes, I can't find any information on the 11/22 number but anyway the 375 is good for now, back to the new flywheel now.
The 200mm flywheel fits the same clutch bearing as the 180mm. The 200mm flywheel needs M7 bolts rather than M8 bolts as there is so little space for the holes between the clutch and the outside of the flywheel. I had exactly the opposite .. a 1979 engine block had a 200mm flywheel. I bought a 180mm..

GSF are my go to place for consumables like clutches and a few other VW T2 parts , as their money off offers are pretty competitive. I also have three within fairly easy driving distance around me. I would do a click and collect because then you know they have the part locally in stock. If not they will redirect you to another store. However some branches dont carry much VW aircooled stock. E.g. Swansea had no idea about fan belts. But neither did Euro Car parts. I was saved by finding a spare fan belt trapped by wiring in my bus, couldnt be bothered to disconnect a single wire from a terminal block saved me..
